The synthesis of the first meso-meso linked core modified smaragdyrins with unusual single photon properties is reported.

Fig. S3 TEM images of (a) meso-tetrakis(pentafulorophenyl)porphyrin (compound 1), (b) N-fused pentaphyrin (compound 2), (c) meso-hexakis(pentafluorophenyl) [26] hexaphyrin (compound 3), (d) mesoheptakis(pentafluorophenyl) heptaphyrin (compound 4) (e) meso-octakis(pentafluorophenyl) octaphyrin (compound 5), and (f) meso-nonakis(pentafluorophenyl) nonaphyrin (compound 6) on IrO2-GaN:ZnO photocata...

The reaction at room temperature of an aromatic aldehyde with pyrrole in the presence of Iodine, acetic acid catalyzed of meso-substituted dipyrromethane. The mixture was ground together in a mortar with a pestle at room temperature for short reaction time and easy operation under at room temperature. The meso substituted dipyrromethane is purified by crystallization and column chromatography o...

Two new paired domain genes of Drosophila, Pox meso and Pox neuro, are described. In contrast to the previously isolated paired domain genes, paired and gooseberry, which contain both a paired and a homeo-domain (PHox genes), Pox meso and Pox neuro possess no homeodomain. Evidence suggesting that the new genes encode tissue-specific transcriptional factors and belong to the same regulatory casc...

The meso (or D,L) isomer of diaminopimelic acid (DAP), a precursor of L-lysine, is a key component of the pentapeptide linker in bacterial peptidoglycan. While the peptidoglycan incorporated in the highly complex cell wall of the pathogen Mycobacterium tuberculosis structurally resembles that of Escherichia coli, it is unique in that it can contain penicillin-resistant meso-DAP-->meso-DAP linka...

Fluorescence properties of meso-tetrafurylporphyrins with N4, N3S and N2S2 porphyrin cores are studied by both steady-state and time-resolved fluorescence techniques and compared with the corresponding meso-tetraarylporphyrins. The study shows that the replacement of six-membered aryl groups with five-membered furyl groups at meso-positions alter the fluorescence properties considerably, as ref...

A Ni/meso-MgO catalyst with high surface area and small Ni nanoparticles was synthesized and investigated for hydrogen production by steam reforming of phenol for the first time. Compared to conventional Ni/MgO, the Ni/meso-MgO catalyst showed higher catalytic activity and stability. X-ray Diffraction, N2 adsorption, hydrogen temperature programmed reduction, transmission electron microscopy an...

Oligoureas (up to n=6) of meso cyclohexane-1,2-diamine were synthesized by chain extension with an enzymatically desymmetrized monomer 2. Despite being achiral, the meso oligomers adopt chiral canonical 2.5-helical conformations, the equally populated enantiomeric screw-sense conformers of which are in slow exchange on the NMR timescale, with a barrier to screw-sense inversion of about 70 kJ mo...

meso-Substituted BODIPY with N-butylcarbazole () was prepared and derivatized. Dibromo BODIPY , α-formyl BODIPY and β-formyl BODIPY were synthesized. All compounds were characterized by HRMS, NMR, UV-vis absorption, electrochemical and fluorescence techniques. The crystal structures of BODIPY and its dibromo derivative were also solved. In both the X-ray structures, the dihedral angle between t...
